The traction control system is part of ABS control module an if the light is on there is A DTC - diagnostic trouble code stored in the EBCM - electronic brake control module ! The brake pedal position sensor is an input to the EBCM , when you press the brake pedal the EBCM then energizes the BAS relay in the left rear fuse box turning on the brake lamps !
There could be a DTC like
DTC B3903
The electronic brake control module (EBCM) supplies voltage to the BAS relay coil side voltage supply circuit when the stop lamps are active. The coil side control circuit of the BASS relay is permanently grounded at G402.
DTC Descriptor
This diagnostic procedure supports the following DTC:
DTC B3903 Stop Lamp Relay Circuit
Or
DTC C0278
The brake pedal position sensor (BPP) is a potentiometer. The electronic brake control module (EBCM) supplies a 5-volt reference circuit and low reference circuit to the BPP sensor. The BPP sensor signal circuit is a direct input to the EBCM. The EBCM determines the BPP based on the voltage from the BPP sensor. The EBCM converts the BPP sensor feed back voltage to a digital signal and puts it on the class 2 communication bus.
DTC C0282 Brake Pedal Position Sensor Circuit Range/Performance
DTC C0283 Brake Pedal Position Sensor Circuit Low
DTC C0284 Brake Pedal Position Sensor Circuit High
DTC C0880 Device Voltage Reference Output 2 Circuit
You may want to take this to the dealer !

SOURCE: CTS in dash navigation system

There is a company called PAC that specializes in modules like you describe - keeping the steering wheel controls functional with an aftermarket radio.

Click HERE to visit their site. You have to choose a compatible manufacturer. Basically - it is turning the steering wheel controls into a "remote" hidden in the dash.

CLICK HERE for the PAC installation guide for the 2006 CTS

For best results and compatibility, look for a shop in your area that carries PAC - it is a common manufacturer in the BIZ, and have them install it.

The simple answer to your question is YES as long as you use the module compatible for the brand of radio you are installing.

SOURCE: 2003 Cadillac CTS - the car won't shift from park

sounds like you have a bad brkae light switch, which is located on the brake pedal assembly. a bad switch will not let you shift out of park and you will not have any brake lights as the car does not recognize that the pedal is being pushed and brakes engaged. easy to replace switch if you are handy, if not this is a inexpensive repair at any mechanic. hope this was helpful is so please rate 4 thumbs.

Low brake fluid level could cause that. Bad ABS wheel sensor. Brake switch. Go to Autozone and ask them to put the scanner on and see what codes you're getting.

2006 CTS Engine light on.


Whenever this warning light or any other stays on in the dash it is indicating that the systems control module (or the system sensor in the case of lights like low oil pressure, door open indicators etc.) has detected a fault, it then disables the system (this applies to ABS,TCS, TCM, SRS, TPMS, MIL, CEL and BCM faults and others) as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

Legend of Abbreviations. ABS Anti-lock brake system. TCS Traction control system, TCM Transmission control module, SRS Supplemental restraint system, BCM Body control module. TPMS Tire Pressure Monitor System, MIL Malfunction Indicator Lamp, CEL Check Engine Light.

well while putting the car on the lift, traction control does not need to be disabled, and will not cause the abs/traction light to illuminate, these cars are known to have terrible wheel speed sensors that are brittle and tend to brake or malfunction for no apperent reason, and the wheel speed sensors are what control your abs and traction conrol units and they are normally what make the light come on on your dash, the warranty on the sensors was prolonged for that reason, so depending on the mileage of your car they might be covered, hope this helps
